United States Patent | 5,033,204 |
Chiappini | July 23, 1991 |
The dehydration process substantially consists in causing the fabric in rope form to continuously advance between at least two pairs of pressing rolls, with it being simultaneously submitted to a false twisting. The false twist causes a wringing of the fabric with the consequent partial evacuation of the liquid the fabric is sodden with. In order to improve the dehydration, a centrifugation of the twisted fabric is provided. The apparatus substantially comprises a twisting organ capable of giving a false twist to the running fabric. The twisting organ can be constituted by a revolving structure capable of causing the fabric to run along a path outside its advancement axis, with the fabric thereby simultaneously undergoing a twist and a centrifugation.
